Frequently Asked Questions About Peterbilt 367 Torque Rods & U-Bolts

What are the signs that my Peterbilt 367 torque rods need replacement?

Common indicators include excessive driveline vibration, clunking noises during acceleration or deceleration, uneven tire wear, and visible bushing deterioration such as cracking, separation, or missing rubber. You may also notice wandering or pulling while driving. Most torque rods last 300,000-500,000 miles under normal conditions, but heavy-duty applications or rough terrain can reduce this lifespan significantly.

Will aftermarket torque rods and U-bolts fit my specific year Peterbilt 367?

Most aftermarket torque rods and U-bolts for the Peterbilt 367 are designed to fit model years 2007-2015, which share the same suspension configuration. However, always verify compatibility by checking your truck's suspension type (Peterbilt Air-Trak, Chalmers, or Hendrickson), axle spacing, and whether you have a single or tandem rear axle setup. The part numbers on your existing components can help ensure proper fitment.

What torque specifications should I use when installing U-bolts on my Peterbilt 367?

Standard torque specifications for Peterbilt 367 U-bolts typically range from 300-350 ft-lbs for 3/4-inch diameter bolts and 450-500 ft-lbs for 7/8-inch diameter bolts. Always tighten in a cross pattern and re-torque after 50-100 miles of operation. These specifications can vary based on suspension manufacturer, so consult your service manual or the component manufacturer's guidelines for exact values.

Should I replace torque rods individually or as a complete set?

While you can replace individual torque rods, it's recommended to replace them in pairs (both sides of the same axle) or as a complete set. This ensures balanced suspension performance and prevents premature wear on new components. Mixing old and new torque rods can cause uneven load distribution and alignment issues. Labor costs are often similar whether replacing one or multiple rods, making complete replacement more cost-effective.

What's the difference between standard and heavy-duty torque rod bushings?

Standard bushings are typically made from natural rubber and work well for highway applications and moderate loads. Heavy-duty bushings use polyurethane or enhanced rubber compounds that resist oil, heat, and compression better than standard versions. Heavy-duty options last 2-3 times longer in severe-service applications but provide a slightly firmer ride. Choose heavy-duty bushings if you frequently haul maximum loads, operate off-road, or experience premature bushing failure.
